The NI SC-2345 Signal Conditioning Carrier is a modular platform that houses and interfaces with National Instruments Signal Conditioning Modules (SCCs) for data acquisition systems. It connects to 68-pin E/M Series DAQ devices and provides signal conditioning across analog and digital I/O channels. The carrier delivers a 5 V ± 2.5 mV onboard reference with ±15 ppm per 1000 hours stability and 4 microvolts peak-to-peak noise performance, supporting measurement applications requiring precision signal integrity.
